SMMA and PMMA Substitution
Problem Phenomenon
SMMA substituting PMMA has cost advantage, but performance difference management.
Cause Analysis
SMMA successfully substitutes general-purpose grade PMMA; cost advantage; but performance differences; application matching; quality verification; customer acceptance.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
①Substitution application assessment; ②performance comparison; ③quality verification; ④cost accounting; ⑤customer communication.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
SMMA substituting PMMA is a cost optimization path; performance matching is the premise; verification keeps success.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
